To all 'whom t mag/concern:

Be it known that I,THoMAs J. Moss, av cifien of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Shocks, of which the following is a specilication, reference being had to the. accompanying drawings. V

This invent-ion comprehends certain new and useful improvements in accessories for automobiles and similar vehicles, and relates particularly to an improved. chock or block for motor cars designed for use in holding the cars stationary while repairing a! tire or in other situa-tions where it is impracticable to set the emergency brakes.

The invention has for its primary object a simple, durable and ellicient construction of device ot' this character, the parts 'of whichl are vso arranged that they may be 'cheaply manufactured and readily .assembled and disassembled, the device being collapsible so that it maybe easilyl carried in the tool box whereit will take up very little room. And the invention also aims to 'generally improve devices of this class and to render; them more useful and commercially ole.

ith these and other objects in view, as wili more 'ully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinaations of the parts that I shall hereinafter- -nlly describe and claim.

For a full understanding of theinvention, reference is to be had to the following description and accompanying drawing, in which, y s

Figure 1 is a longitudinal sectional view of Aone forni or 'embodiment' Aof my invention. Fig. 2is an end view thereof. Fig. 3 a detail perspective view of the brace plate or strut employed with the modifica-l tion illustrated in Figs. land 2. Fig. 4 is a sectional view of another" view of the device, and, Fig. 5 is an end viewthereof.

Corresponding and like parts are-referred to in the following descrlption and designated in the accompanying drawing by like reference characters.

In that embodiment of the' invention illustrated in 'I ig. 1, the device comprises two plates designated 1 and 2, the same being preferably formed of sheet metal and be- Aing `hingedly or otherwise movably conlormay be set up b nested together at one edge, as indicated at 4 which 'are designed to receive and de-` tachably hold lugs 5 that are formed on two side edges of a.. substantially triangular brace plate lor strut 6, whereby when said brace plate is inserted-in betweenthe plates 1 and 2 and its lugs 5 engaged in the slots 4, the said plates will be heldin angular relation to each other and may effectively serve as a wedge or chock against a-wheel of the automobile.

In that embodiment of my' invention illustrated in Fig. 4, the brace plate, there desi nated 6*, is hingedly connected to one of t e plates and is formed with lugs 5* designed for engagement in slots 4f in the other plate. In other respects,this device is like that illustrated in Fig. l.

From the foregoing description in' con nection with lthe accompanying drawing, the operation of my im roved chock will be apparent. plates 1 and 2 together and by hin edly connecting the brace late to one o the4 lates 4so as tov swin aterally thereon, orL

y forming the sai' x edges with the lugs` before mentioned, it is obviousthat the device may be folded, one part uponvanother, and carried in` av very ycompact. condition in a :tool box or4 other receptacle. When the device` is re- By hmgely connecting the brace plate on two quired for use, it may be easily set up,.

either by inserting the brace plate' in bement of the invention illustrated in- Fig. 1, v

opening plates 1 and 2 and swinging -the race platef to a right angular position relative to the plate 1 and then inserting the lugs 5l into the slots 4".

While the accompanyingvdrawing illustrates what I believe to be the preferred embodiment of my invention, it 'isto be un-A derstood thatv the invention isl not limited thereto, but that various changes may be made in the constructiom,arrangement and proportions of theparts without departing from thc sco e'of the invention,.as. defined in the appen ed' claims. f

-What I claim is 1. A chocklfor vehicle wheels, comprising sheet metal plates movablconnected together at one edge,.and a s eet metal brace plate of' triangular formation designed for los insertioirin between the first named plates orL connectng\sai brace with the of sheet.y metalf'plates hngedly'connected 15 together(- on one edge, sald lates' 'bem formed vinterrnedafteofl their sie'edges anV in Line Wvthfeach other With'slojss, and a triangular 'brace-plate designed for insertion" iu between the hinged plates and 20 formed' wthy-edge lugs adapted tov engage Ingtestimoy whereof I hereunto aix my sgnfture in theiiresence of two witnesses.
